Application of Variable Damping Hydraulic Buffer in Braking Large Mass Impact Loading Problem

摘要

Aimed at braking large mass impact loading problem, a mathematical model of the multi-orifice hydraulic buffer has been established, with the use of hydrodynamics theory, hydraulic theory and engineering structural mechanics theory. Damping characteristic curves under different operating conditions have been analyzed. The problem that traditional hydraulic buffer damping characteristics could not match to different mass impact loading well has been found. By analyzing the influence of buffer cylinder structural parameters on buffer damping characteristics, a variable damping buffer has been proposed, and the problem has been verified with simulation.
